Definitions

  • the present invention relates to a pickup baler for making parallelepipedic bales of crop material, as described for example in U.S. Pat. No. 4,132,164 granted on Jan. 2, 1979 to WHITE, the contents of which is incorporated herein by reference.
  • the fodder is gathered up from the ground by a lifting cylinder or pickup, then introduced and precompressed within a precompression channel opening out laterally into a baling chamber where a baling plunger moves in reciprocating motion.
  • a feeding mechanism transfers the charge present in the precompression channel into the baling chamber.
  • the transfer time corresponds to the short return time of the piston, with the result that the feeding mechanism operates at high speed.
  • the feeding mechanism conventionally comprises a series of fingers which penetrate slots extending over the length of the precompression channel and sweep this channel under the action of an eccentric drive.
  • the resistance exerted by the charge depends in the first place on the rate of precompression attained in the precompression channel.
  • this resistance increases sharply when the rate of hygrometry of the cropped material increases beyond a certain threshold, without the causes of such a sharp increase being clearly elucidated.
  • the fact of exceeding a certain threshold of hygrometry results in a coalescence or packing of the cropped material, as well as adhesion thereof against the walls of the precompression channel.
  • the walls of the precompression channel are at least partially made of a material which presents a low surface tension with respect to water, or are coated with such a material.
  • the effect of adhesion of the cropped material against the walls of the precompression channel will be considerably reduced, as well, consequently, as the resistance exerted by the charge on the feeding mechanism during transfer of the charge towards the baling chamber, thus overcoming the drawbacks of the prior art.
  • materials for making or coating the walls of the precompression channel materials will be chosen which preserve a good resistance to abrasion, such as for example polyamides (nylon) of high molecular mass or polyethylenes.
  • Composite materials may also be chosen which comprise coated glass fibers in a matrix of plastics material.
  • a metallic material may also be chosen having received a special surface treatment or an application of special paint or lacquer.
  • the teachings of the invention will be applied in priority to the concave wall located opposite the feeding fingers insofar as the friction of the cropped materials against this wall has a preponderant effect.
  • FIGURE of the accompanying drawings is a view in longitudinal section of a pickup baler incorporating an improvement according to the present invention.
  • the machine is essentially constituted in accordance with U.S. Pat. No. 4,132,164 to which reference is made for further details.
  • a parallelepipedic baling chamber 16 in which moves a plunger 18 in reciprocating motion in order to compress the fodder in the form of parallelepipedic bales 20 which are then evacuated via the rear end of the machine, towards the right in the FIGURE.
  • Beneath the chassis 10 are fixed a certain number of devices for gathering the cropped material from the ground and for conducting it to the baling chamber 16.
  • these devices comprise successively:
  • the pickup device 22 comprises a shaft 28 provided with a plurality of radial rods 30 and driven in rotation in clockwise direction. It is maintained at a short distance above the ground, so that, when the machine is moving, i.e. towards the left in the FIGURE, it lifts the material, previously cropped and windowed, above the ground and directs it towards the rear in the direction of the precompression device 24.
  • the latter comprises a supply mechanism 32 and a precompression channel 34.
  • the supply mechanism comprises a cylinder 36 placed immediately above the inlet of the precompression channel 34, driven in rotation in anticlockwise direction, and bearing supply fingers 38 which project over a variable distance from the cylinder 36 so that the fingers are in maximum extension on the pickup device 22 side and in complete retraction on the precompression channel 34 side.
  • the precompression channel forms a substantially quarter-circle bend and terminates in an outlet 40 in the lower face of the balin chamber.
  • the kinematics of the baling plunger are such that the plunger closes the outlet 40 during its forward strokes in the chamber and uncovers this outlet at the end of its return strokes.
  • the role of the supply mechanism 32 is therefore progressively to force the cropped material into the precompression channel 24 and to constitute therein a charge of precompressed material which is packed progressively against the baling plunger, which serves as stop to that end.
  • the feeding mechanism 26 comprises arms 42 bearing fingers 44 and driven by a drive device which imparts to the arms a complex movement indicated in broken lines at the figure in synchronism with the reciprocating strokes of the plunger 18, as described in detail in U.S. Pat. No. 4,132,164 mentioned hereinabove.
  • this movement includes an active section during which the fingers 44 first penetrate the channel, near the base thereof, passing through longitudinal slots extending over the whole length of the upper wall of the channel, and thereafter the fingers sweep the channel on rising therealong, to push the precompressed charge into the baling chamber through the outlet 40 whilst the latter is uncovered since the plunger 18 is in its retracted position.
  • the movement of the arms then includes an inactive return section during which the fingers leave the precompression channel in the vicinity of its outlet, then swing downwardly, outside the channel and as far as the base thereof.
  • the active movement of the arms is effected in a very short time and it will be observed that the efforts coming into play reach a maximum value at the beginning of this active movement when the fingers penetrate the channel and begin their ascending sweeping movement.
  • the ratio between the resistant lever arm and the driving lever arm on the arms of the mechanism is at that moment the highest.
  • any increase in the resistance that the precompressed charge exerts against its transfer towards the baling chamber may lead to deteriorations of the drive elements, which are usually avoided by providing in the kinematic chain an element of least resistance or sacrificial element of which the rupture protects the other elements.
  • the sacrificial element is not shown on the drawing.
  • the walls of the precompression channel are at least partially made of a material presenting a low surface tension with respect to water.
  • the walls of the precompression channel are made of sheet metal and the concave wall 46 located opposite the feeding fingers 44 is coated with a plate 48 of a material as defined above.
  • This embodiment can easily be adapted to all machines, both during manufacture and during subsequent re-fitting, without necessitating long immobilization of the machine.
  • the material in question may consist of a composite formed by plastics material reinforced with glass fibers or in general high-strength fibers;
  • a preferred material is polyamide (nylon);
  • the coating may be applied on the walls in the form of paint, lacquer or in the form of a special surface treatment.
